fs/ntfs3: Use new api for mounting

We have now new mount api as described in Documentation/filesystems. We
should use it as it gives us some benefits which are desribed here

Nls loading is changed a to load with string. This did make code also

little touch and is not mandatory but it should not make any harm. It
is just convenient that we can use example acl/noacl mount options.
